2. Ensure the cleanliness of the fuel. Filter through sediment or silk cloth if necessary.
3. Maintain normal water temperature (70～85℃) and oil pressure (0.2～0.4MPa at medium speed).
4. During operation, if any abnormality is found, stop and check immediately.
5. "Hard water" should not be used as cooling water to prevent scale formation and reduce the service life of the engine.
Second, daily maintenance
